To all w'wm'z may concern.'

h Be it known that l, WARREN D. Dense, a citizen of the United States,residing at Farmington, in the county of St. Francois and State ofMissouri, have invented a new' and useful Method of Making rllires, ofwhich the following is a specication.

lt is the object of thisA invention to provide a novel method for makinga strong and relatively perfect tire out of two imperlect tires, one ofwhich is injured adjacent its beads, the other of which is injured inits tread portion.

With the above and other objects in view,

the invention consists in theprocess hereinafter described, and in thesteps thereof, 1t being understood that, within the scope of what 1sclaimed, a mechanic might work such changes as his skill suggests,without departing from the spirit or the invention.

ln the accompanying drawings Figure l shows in side elevation, astructure wherein the process has been carried out, parts being brokenaway successively; Fig. 2 is a cross section of the device shown in Fig.l. I

ln carrying out the present method there is employed a nrst tire casing5 having beads d, and a second tire casing 3, the i1nperlect beads ofwhich are-cut o','the casin` 3 Vbeing beveled in the cutting operation,as shown at 6./ A layer of vulcanizable matebetween the casings 3 and',the second casnog` 3 beingsuperposed on the first casing 5. The firstcasing 5 issustained internally in any desired way, preferably by meansor a exlble core whichinay consist-,of a bag l inclosing a mass of sand2, rlhe core, howf ever, may be made as desired.

'lhe spacesbetween the beads d of the first .casing 5 and the secondcasing-gare bridged by -means of plates 9, ordinarily made of galvanizediron 'or some other suitable .inaterial. 'llhe casings 5 and 3 and thebridge plates 9 are wrapped in any desired way, -1

preferably by means or aspirally disposed specification oi lettersEEatent.

The structure thus produced is vulcanized, in a kettle or otherwise, thewrapping 11, the plates 9 and the spacers l0 being removed, after theprocess of vulcanization has been completed.

The process above described affords a simple method whereby a relativelyperfect tire easing may be inade out of two casings which are damagedmore or less, and it is to be observed that, owing to the use of thebridgingplates 9 and the spacers l0, the

Istructure to be vulcanized will be held in proper shape, about the corel-2, adj aeent to the beads 4, during the process of vulcanization totighten the tape; subjecting the structure thus produced tovulcanization; and removing the tape, the plates and the spacers.

Having thus described the invention, what A method of combining a firstimperfect tire casin .havin beads with a second irn-y lirst casinginternally; bridging the spaces between the beads of the irst casing andthe second casing with plates; wrapping the casings and the plates;sustaining the plates internally; sub] ecting the structure thusproduced to vulcanization; unwrapping the casings and the plates; andremoving the plates and the sustaining means.
